Jennifer Garner Warns Chrissy Teigen Over Nanny-Stealing: 'Don't Get Any Ideas'

Jennifer Garner's nanny is a big fan of Chrissy Teigen, and it's making the actress nervous.

Garner recently realized that the nanny of her children with ex-husband Ben Affleck liked Teigen's Instagram a little too much, especially the model's posts about her children. The "Love, Simon" actress then jokingly warned the "Lip Sync Battle" host not to "get any ideas" about stealing her employee.

"I see my kids' nanny liking everything you put up with your gorgeous kids," Garner commented on Teigen's latest Instagram post. "And I'm here to tell you, don't get any ideas, either one of you."

As a response to Garner's comment, John Legend's wife announced on social media, "For anyyyyyyone reading this I ONLY POST THE CUTE STUFF."

Teigen's latest post was indeed "cute" as it showed her son Miles, 10 months, looking super adorable while nestled in a box. The photo, which Teigen posted Sunday, has been liked by over a million of the model's followers and received thousands of comments, most of which praised little Miles.

In her caption, Teigen also pointed out that while Miles looked very much like her husband's mini-me, he did inherit her nose.

Prior to sharing her latest update about her son, Teigen also posted a video of her eldest child, daughter Luna. It was apparently a "big day" for Luna as she got to see her newly renovated room.

But when asked what she thought of her room, the adorable toddler was more concerned about her missing bed buddies. She searches the room for her stuffed animals, and after finding them, gathers them up to put them back where they belonged: her bed.

After her parents help her out, Luna sweetly thanks her parents and sits on her bed.

Unlike Teigen's babies, Garner's children, Violet, 13, Seraphina, 10, and Samuel, 7, have all outgrown boxes. According to the "Alias" alum, her son even finds it uncool when she puts on costumes now.

Samuel celebrated his 7th birthday weeks ago, and it had the theme "How To Train Your Dragon." Garner did her best to follow the theme and dressed up as the viking warrior Astrid, donning red leather armor, fur boots, a matching shawl and blue face paint.

Garner shared a photo of herself in full costume carrying a dragon-designed cake. However, she said in her caption that Samuel was not impressed with her ensemble for his party.

But while he may not think it's cool for his mom to dress up as cartoon characters anymore, Samuel is still very close to Garner. The mother-son duo was recently spotted taking their dog for a walk in Los Angeles.
